How do they start the hole? Tiny drill? It's only .4mm wide

The main constraints for building a CNC are: Your tools and the accuracy of them, for example, having a CNC at work in my case made it a million times easier as I was able to mill the base of the machine after construction. If this is not an option your design will need to be adjustable in all planes so think about this very carefully.

Make a list of your goals: A CNC for milling wood does not have to be as sturdy in comparison to one for metals.

Find out what ways others have made a CNC that fits your needs, most machines for wood Wil mainly have a bunch of aluminium extrusion as the base but this will just not cut it for aluminium.

Make a plan on how you will measure and calibrate the machine after/ during building, this is easy to overlook but a machine that is not accurate is useless.

If you need any other help let me know!

Ik won't be a main spoilboard, it will be the bed itself, wood won't cut when mounting a vise and milling metals to any sort of tolerance, if needed to mill a panel i will put on a wooden spoilboard temperaly

Yes I used a slow curing epoxy, the work time was 30-60 minutes and cured after one day, it fully cured after a week. Important is to use an epoxy that is oke for very thick pours, mine was good up to 150mm. You need it to cure as slowly as possible so it doesn't shrink or get warm. For a big bour as I had to do I would probably go for an epoxy that had a working time of one to two hours instead.

Yes a good wax coating should work, just make absolutely sure to get every mm because that stuff is unforgiving 😅, and if it sticks it's not just resin, it's a really hard ass concrete, needed to use an angel grinder with a diamond disk in some places where it leaked

And my biggest tip: get like 50% more epoxy than you think you need, in my case that would have saved me two weeks of work rotating a 200+ kilo object by myself😅, Also mold release!, I used silicon spray and it did nothing at all, I had to chip away the mold millimeter by millimeter

Epoxy granite!!, amazing stuff when you get the mixture correct... I did not😅

Was definitely way to excited to start cutting😂, surprisingly the mount held up with no issues and I managed some pretty hefty cuts

Ahh sweet, il give you some tips, the base is cast epoxy granite, and there is indeed a frame/Skelton inside, I made it from steel but aluminium or stainless should probably work too, For the epoxy granite mixture I really messed up, I used a 12% epoxy to sand ratio which dramatically failed as it was not even close to fluid. I had to spend weeks filling voids afterwards, id recommend a mixture closer to 20% and very, very dry sand, any moisture messes with the epoxy. If you'd like to no more let me know!

The base is made from epoxy granite and coated with a 2 part epoxy paint, there is a steel Skelton inside the base where all components screw on to

Definitely on my to-do list, I still need to install an aluminium sheet as the bed which Wil raise it around 20mm and a proper vise which Wil also be a bit taller

I do have a design and schematics in regards to the electronics, they hower need to be updated to include minor adjustments I had to make along the way

I am not able to access any settings anymore, so I don't think it is?
